Simulation Study On Integral Hoisting Construction Process Of A Large Truss

In the new century, with the rapid development of China’s national economy, the construction industry as a pillar industry has being developing rapidly the construction product increasingly pursues the personalization, the use of the variety new materials and new structures make the projects complex. The construction technique and the management has also had the tremendous change, we need the effective analysis method to instead the old one.At the same time,it is difficult for the large-scale project to get a reasonable and intuitive results because of the large number of staff,a wide range of a professional and so on.This article describes the development and application status of the virtual construction technology at home and abroad, Introduction of large space structures commonly used in co nstruction methods and features, combined with the virtual construction technology Poly Cultural Plaza in Wuhan to connect the body as a whole lifting construction process simulate on analysis; modeling calculation of the structure assembled on the ground as a whole stage nod enhance the stage component of the internal force and displacement, were calculated an d compared whether the vertical integral lifting the temporary support, temporary vertical sup port structure does not meet the specification requirements, you must increase the tempor-ary support based on the results; consider the wind load in order to ensure construction from time to time to prevent the wind loads on the construction needs to add to embrace wind rope. The calculated results with reference to the value of improved construction pro gram can be applied to practical engineering. Make a simulation study on the connect bo-dy integral lifting construction process of Wuhan Poly Cultural Plaza. Modeling calculate on of the structure assembled on the ground as a whole stage and enhances the stage compo-nent of the internal force and displacement. I calculated and compared on whether the verti cal integral lifting the temporary support, Based on the results no temporary vertical suppor t structure does not meet the specification requirements, so we must increase the tempora ry su-pportpieces And consider the wind load in order to guarantee to prevent the constructi on of wind loads on the construction, According to the calculated displacement under wind loads, needs to add to embrace wind rope, Calculated results with reference to the value of improving construction progress, can be applied to practical engineering.
